Abstract

Przedmiotem zgłoszenia jest nowatorski sposób otrzymywania zmodyfikowanego oleju jojoba o poprawionych właściwościach niskotemperaturowych i utwardzonego wosku, w którym to sposobie będący surowcem olej jojoba, charakteryzujący się temperaturą mętnienia ok. 9°C, temperaturą płynięcia ok. 8°C i temperaturą krzepnięcia ok. 7°C poddaje się procesowi rozdzielania rozpuszczalnikowego na filtrat - roztwór zmodyfikowanego oleju jojoba i osad - wosk utwardzony zawierający pozostałości rozpuszczalnika, obejmującemu etap krystalizacji i etap filtracji, przy czym w etapie krystalizacji surowiec poddaje się pierwszemu rozcieńczeniu rozpuszczalnikiem zawierającym 15% - 85% (m/m) dichloroetanu i odpowiednio 85% - 15% (m/m) chlorku metylenu, uzyskując mieszaninę surowca i rozpuszczalnika, którą następnie oziębia się z kontrolowaną prędkością, z równoczesnym doprowadzeniem oziębionego rozpuszczalnika w 1-6 porcjach kolejnego rozcieńczenia, przy szybkości schładzania w zakresie 0,12 — 6,8°C/min, aż do osiągnięcia temperatury od -14 do -30°C, przy czym stosunek sumarycznej ilości rozpuszczalnika z rozcieńczeń i przemywania do surowca zawiera się w przedziale od 2,2:1 do 9,8:1 (m/m), przy czym wielkość każdego jednostkowego rozcieńczenia wyrażona stosunkiem masowym rozpuszczalnika do surowca wynosi od 0,2:1 do 4,5:1 (m/m), po czym w zakresie temperatur od -14 do -30°C odfiltrowuje się wydzielony osad, który przemywa się zimnym rozpuszczalnikiem o takim samym składzie jak rozpuszczalnik używany w etapie krystalizacji, stosowanym w ilości od 0,15:1 do 4,0:1 (m/m), wyrażonej stosunkiem masowym rozpuszczalnika do surowca, a następnie z filtratu oddestylowuje się rozpuszczalnik uzyskując produkt końcowy, którym jest zmodyfikowany olej jojoba o obniżonych: temperaturze mętnienia od 4 do 10°C, temperaturze płynięcia od 5 do 10°C i temperaturze krzepnięcia od 5 do 11°C, oraz następnie z osadu oddestylowuje się rozpuszczalnik uzyskując wosk utwardzony o podwyższonych: temperaturze mętnienia od 4 do 5°C, temperaturze płynięcia od 2 do 4°C i temperaturze krzepnięcia od 1 do 3°C w stosunku do wartości tych temperatur przed poddaniem surowca, oleju jojoba procesowi rozdzielania rozpuszczalnikowego na filtrat i osad oraz oddestylowanie z nich rozpuszczalnika.The subject of the application is an innovative method of obtaining modified jojoba oil with improved low-temperature properties and hardened wax, in which the jojoba oil being the raw material, characterized by a cloud point of approx. 9°C, a pour point of approx. 8°C and a solidification point of approx. 7°C C is subjected to a solvent separation process into a filtrate - a solution of modified jojoba oil and a precipitate - hardened wax containing solvent residues, including a crystallization stage and a filtration stage, where in the crystallization stage the raw material is first diluted with a solvent containing 15% - 85% (m/m ) dichloroethane and 85% - 15% (m/m) methylene chloride, respectively, obtaining a mixture of raw material and solvent, which is then cooled at a controlled rate, with the simultaneous supply of cooled solvent in 1-6 portions of the next dilution, at a cooling rate in the range of 0 .12 - 6.8°C/min, until reaching a temperature of -14 to -30°C, where the ratio of the total amount of solvent from dilutions and washings to the raw material is in the range of 2.2:1 to 9.8 :1 (m/m), where the size of each unit dilution expressed in the mass ratio of solvent to raw material is from 0.2:1 to 4.5:1 (m/m), then in the temperature range from -14 to -30 °C, the separated precipitate is filtered off and washed with a cold solvent of the same composition as the solvent used in the crystallization step, used in an amount of 0.15:1 to 4.0:1 (m/m), expressed as the mass ratio of solvent to raw material and then the solvent is distilled from the filtrate to obtain the final product, which is modified jojoba oil with reduced: cloud point from 4 to 10°C, pour point from 5 to 10°C and solidification point from 5 to 11°C, and then with the solvent is distilled off to obtain hardened wax with increased: cloud point from 4 to 5°C, pour point from 2 to 4°C and solidification point from 1 to 3°C in relation to the values of these temperatures before subjecting the raw material, jojoba oil, to the separation process into the filtrate and precipitate and distilling off the solvent from them.
